The real hobo pie is a special kind of sandwich. Normally made in the firepit. A cooker with long handles attaches to iron plates (shaped like a small frisbee) on each side, it is attached together at the fire end of the utensil so you can securely close it before putting it in the fire. You place buttered bread in each 1/2 (to cut down on sticking), and between the bread any assortment of food (turkey and cheese, or ragu sauce with cheese and meat). Then close the handles to secure it, and roast it over your campfire. After a few minutes you open it up and pop out your authentic Hobo pie. Very popular in Midwest campsites, especially after late night drinking.
